Abstract
Description
Technical Field
[0001] This invention relates to the field of glass processing equipment technology, specifically to a laser cutting device for irregularly shaped glass and its control system. Background Technology
[0002] Laser cutting technology is often used for processing irregularly shaped glass. When thin glass is laid flat on the worktable for processing, the glass surface will have height fluctuations due to the internal stress of the material and the processing tolerance of the supporting table. When processing thin glass, existing laser cutting equipment relies on gravity to lay it flat or uses rigid pressure components to fix it. It lacks a pressure structure with adaptive compensation capability. When the laser cutting head moves along the set processing trajectory, the height change of the glass surface will directly cause the vertical position of the laser focus to change. The focal length shift will lead to uneven kerf depth or even local incomplete cutting, reducing processing accuracy. After laser cutting of irregularly shaped glass, the waste and finished glass are still embedded in the same plane. To separate the waste, traditional equipment relies on mechanical structures such as ejector pins or suction cups to apply external force. However, the complex cutting contours of irregularly shaped glass mean that relying on mechanical force will cause uneven stress on the material, resulting in chipping and breakage at the edges of the finished glass. Contact between mechanical parts can also scratch the surface of the finished glass. After the waste is separated, the remaining waste fragments in the working area need to be manually cleaned periodically by stopping the machine, or a separate transfer mechanism can be configured to remove the waste. The waste collection action and the finished product output action will interfere with each other, making it impossible to complete the separation of waste and finished product simultaneously, increasing the process flow time and reducing the continuity of equipment operation. Summary of the Invention
[0003] To address the shortcomings of existing technologies, this invention provides a laser cutting device and control system for irregularly shaped glass, which solves the problems of existing laser cutting equipment for irregularly shaped glass being unable to adaptively compensate for glass surface undulations, resulting in unstable cutting focal length, and relying on mechanical external force to separate waste materials, causing damage to finished products and poor continuity of waste material collection.
[0004] To achieve the above objectives, the present invention provides the following technical solution: The first aspect of the present invention provides a laser cutting processing device for irregularly shaped glass, including a housing, a cutting table installed on the top of the housing, a moving mechanism provided on the housing, and a cutting workpiece for laser cutting the glass connected to the moving mechanism. The cutting workpiece includes a laser cutting head and a flexible pressure cover. A spring and a ball are provided inside the flexible pressure cover, and a cleaving execution head is provided on the inner wall of the cutting workpiece. The bottom of the housing is equipped with a conveying mechanism for lifting the glass sheet and transporting it to the processing coordinate area; A waste separation zone is provided on one side of the top of the shell. Multiple execution components are installed inside the waste separation zone. These components are used to locally heat the area around the waste and centrally cool the waste area, creating a temperature difference between the waste area and the surrounding finished product area, and causing the waste to break and separate from the finished glass. A waste collection frame is provided below the waste separation zone. Multiple conveyor belts are provided on the side of the shell near the waste separation zone, with gaps between them. The waste collection frame is located directly below the multiple conveyor belts.
[0005] Furthermore, the moving mechanism includes a transverse slide rail, which is fixedly connected to both sides of the housing. A slider is slidably connected to the outer wall of the transverse slide rail. A support plate is fixedly connected to the top of the two sliders. A longitudinal slide rail is fixedly connected to the top of the support plate. A fixing block is slidably connected to the outer wall of the longitudinal slide rail. The bottom of the fixing block is slidably connected to the top of the support plate. A first vertical slide rail is fixedly connected to one side of the fixing block. A cutting workpiece is slidably connected to the outer wall of the first vertical slide rail.
[0006] Furthermore, a second vertical slide rail is slidably connected to the inner wall of the cutting workpiece, a laser cutting head is fixedly connected to the bottom of the second vertical slide rail, and a flexible pressure cover is fixedly connected to the outer wall of the laser cutting head.
[0007] Furthermore, the outer walls of multiple balls are tumblingly connected to the inner wall of the flexible pressure cover. The balls are spherical, with most of their portion located inside the flexible pressure cover. The middle of the balls engages with the flexible pressure cover, keeping them inside and allowing them to rotate within it. The tops of multiple springs contact the inner wall of the flexible pressure cover, and the bottoms of multiple springs contact the outer walls of multiple balls. The number of springs corresponds to the number of balls.
[0008] Furthermore, after the laser cutting is completed, the moving mechanism drives the cutting workpiece to move, and the cutting workpiece drives the cleaving head to run along the cutting trajectory to induce stress in the microcracks generated by the laser cutting.
[0009] Furthermore, the conveying mechanism includes a base plate, a cylinder is fixedly connected to the top of the base plate, a fixed plate is fixedly connected to the drive end of the cylinder, and multiple conveying plates are fixedly connected to the top of the fixed plate. The outer walls of the multiple conveying plates are slidably connected to the inner walls of the housing and the cutting table. The surfaces of the multiple conveying plates are integrated with a transmission track or roller structure, which is used to provide the power for horizontal conveying.
[0010] Furthermore, multiple conveyor belts are provided on the side of the shell near the waste separation zone, with gaps between the multiple conveyor belts. The waste frame is located directly below the multiple conveyor belts to catch waste fragments that fall through the gaps.
[0011] Furthermore, two positioning blocks are fixedly connected to one side of the shell, and the outer walls of the two positioning blocks are slidably connected to the outer wall of the waste frame. Two clamping plates are slidably connected to the inner wall of the waste frame, and the outer walls of the two clamping plates are slidably inserted into the inner walls of the corresponding positioning blocks.
[0012] Furthermore, an operating panel is provided on one side of the housing, and the operating panel is electrically connected to the control system of the device via a signal line.
[0013] A second aspect of this invention provides a control system for a laser cutting device for irregularly shaped glass. The device includes a moving mechanism, a cutting workpiece, a first vertical slide rail, a laser cutting head, a flexible pressure cover, springs, balls, a splitting execution head, a waste separation zone, multiple execution components disposed within the waste separation zone, multiple conveyor belts, a conveying mechanism, cylinders, a conveying plate, a cutting table, and a waste frame. The control system uniformly schedules the conveying mechanism, the moving mechanism, the cutting workpiece, and the waste separation zone according to a set timing sequence to achieve the following control: The cylinder that controls the conveying mechanism drives the conveyor plate to rise and fall. The conveyor belt or roller structure on the surface of the conveyor plate is used to push and transport the glass sheet to the processing coordinate area and place the glass sheet flat on the cutting table. The control mechanism performs X-axis and Y-axis interpolation to move the workpiece to the center of the cutting path. Control the downward movement of the workpiece to make the ball bearings inside the flexible pressure cover contact the glass sheet and compress the spring, pressing the glass sheet flat on the cutting table, and then cutting it in conjunction with the laser cutting head; The dicing head is controlled to move along the cutting trajectory to induce stress in the microcracks generated by laser cutting. The control conveyor transports the cut glass to the waste separation zone. Multiple actuators inside the waste separation zone locally heat the area around the waste and centrally cool the waste area, creating a temperature difference between the waste area and the surrounding finished product area, causing the waste to break and separate from the finished glass. The control conveyor plate and multiple conveyor belts work together to allow waste fragments that can pass through the gaps between the multiple conveyor belts to fall into the waste frame under the action of gravity. The finished glass is supported by multiple conveyor belts and output.
[0014] This invention provides a laser cutting device for irregularly shaped glass and its control system. It has the following beneficial effects: 1. This invention provides a flexible pressure cover on the outer wall of the laser cutting head, and a spring and ball bearings are arranged inside the flexible pressure cover. When cutting and pressing down, the ball bearings contact the glass surface and roll. The upward reaction force of the glass compresses the spring, and the pressure generated by the spring presses the glass around the laser focus onto the cutting table. The expansion and contraction of the spring can compensate for the height fluctuations of the glass surface, prevent the laser focus from changing vertically, maintain the stability of the focal length and cutting accuracy, and at the same time, the rolling contact of the ball bearings avoids scratching the glass surface.
[0015] 2. This invention sets up a waste separation zone at the top of the shell, and uses the execution components to locally heat the area around the waste while simultaneously cooling the waste area, creating a temperature difference between the waste area and the surrounding finished product area. The temperature difference causes the material to expand and contract with heat, and the thermal stress causes the waste to break and separate from the finished glass along the cut, avoiding damage to the edges of the finished glass caused by mechanical external force peeling.
[0016] 3. This invention sets up multiple conveyor belts with gaps between them on one side of the housing, and sets up a waste box below the conveyor belts. When the broken glass is transported to the top of the conveyor belt, the smaller waste fragments lose their bottom support and fall into the waste box by gravity through the gaps for collection. The finished glass with a size span larger than the gaps is supported by the conveyor belt and continues to be output, thereby realizing the separation of waste and finished glass and reducing manual intervention.

[0019] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0020] Please see the appendix Figure 1 To be continued Figure 4 This invention provides a laser cutting processing device for irregularly shaped glass, including a housing 1. Its internal space and external frame are used to accommodate and support the coordinated operation of a conveying mechanism 8, a moving mechanism 3, a cutting workpiece 5, and a waste separation zone 6. A cutting table 85 is installed on the top of the housing 1, thereby providing global static support for the flat placement of the glass sheet after the conveying plate 84 descends to below the surface of the cutting table 85. The housing 1 is provided with a moving mechanism 3 so that it can be driven by the control system to perform straddle addressing action. The moving mechanism 3 is connected to the cutting workpiece 5, which can be driven by the guide rail to sink to the working reference surface to carry out pressing and cutting actions. The cutting workpiece 5 is used to perform laser cutting processing on the glass. The bottom of the housing 1 is provided with a conveying mechanism 8, which can receive the control signal and start when the glass sheet to be processed is fed. The conveying mechanism 8 is used to lift the glass sheet and transport it to the processing coordinate area. A waste separation zone 6 is provided on one side of the top of the shell 1. The structural design ensures that there is no interference between the side of the cutting workpiece 5 near the waste separation zone 6 and the waste separation zone 6. Multiple execution components adopt existing structures that can output hot and cold media and are integrated inside the waste separation zone 6. One part locally heats the area around the waste, while the other part centrally cools the waste area, creating a temperature difference between the waste area and the surrounding finished product area. The waste is broken and separated from the finished glass by the thermal expansion and contraction effect. A waste frame 9 for collecting waste is provided below the waste separation zone 6. The moving mechanism 3 includes a transverse slide rail 31, which serves as a guide for translation in the X-axis direction. The transverse slide rail 31 is fixedly connected to both sides of the housing 1 to ensure the structural stability of the overall straddle movement. A slider 32 is slidably connected to the outer wall of the transverse slide rail 31. The two sliders 32 are driven by a power source to move synchronously along the transverse slide rail 31. A support plate 4 is fixedly connected to the top of the two sliders 32, so that the support plate 4 can move straddle along the X-axis. A longitudinal slide rail 33 is fixedly connected to the top of the support plate 4 to guide the sliding in the Y-axis direction. A fixing block 34 is slidably connected to the outer wall of the longitudinal slide rail 33. The fixing block 34 can be accurately positioned through the linkage interpolation of the X and Y axes. The bottom of the fixing block 34 is slidably connected to the top of the support plate 4 to increase the guiding stability during the movement. A first vertical slide rail 35 is fixedly connected to one side of the fixing block 34 as a vertical drive guide for the Z-axis pressing and cutting action. A cutting workpiece 5 is slidably connected to the outer wall of the first vertical slide rail 35. The inner wall of the cutting workpiece 5 is slidably connected to a second vertical slide rail 36, which can slide vertically along the inner wall of the cutting workpiece 5. The power source drives the cutting workpiece 5 to slide vertically along the first vertical slide rail 35, and the power source drives the second vertical slide rail 36 to slide vertically relative to the cutting workpiece 5. A laser cutting head 51 is fixedly connected to the bottom of the second vertical slide rail 36. The laser cutting head 51 slides vertically with the second vertical slide rail 36 and outputs laser to perform cutting action. A flexible pressure cover 52 is fixedly connected to the outer wall of the laser cutting head 51. Multiple ball bearings 54 are spherically connected to the inner wall of the flexible pressing cover 52. Most of the ball bearings 54 are located inside the flexible pressing cover 52, with the middle portion engaging with it to prevent them from detaching. The ball bearings 54 can rotate within the cover, while the portion outside the cover rolls against the glass surface. This ensures smooth rolling and prevents scratches during the pressing process. The flexible pressure cover 52 is equipped with multiple springs 53 inside. The springs 53 use the compression deformation generated by the upward pressing force to output the downward mechanical clamping force. The top of the multiple springs 53 is in contact with the inner wall of the flexible pressure cover 52, and the bottom of the multiple springs 53 is in contact with the outer wall of the multiple balls 54. Thus, the extension and contraction of the internal springs 53 compensate for the micro-undulations of the glass, reduce the vibration caused by the micro-undulations of the glass near the cutting point and improve the focal length stability. The number of springs 53 corresponds to the number of balls 54. The inner wall of the cutting workpiece 5 is provided with a cleaving execution head 55. The cleaving execution head 55 adopts an existing cleaving structure, which can be a roller cleaving structure in this embodiment. After the laser cutting is completed, the moving mechanism 3 drives the cutting workpiece 5 to move. The cutting workpiece 5 drives the cleaving execution head 55 to roll along the cutting trajectory, apply pressure to the microcracks generated by the laser cutting to induce stress, so that the microcracks further expand along the cutting trajectory, providing a fracture basis for subsequent hot and cold medium intervention and separation. The cleaving execution head 55 does not directly separate the waste from the finished glass. The conveying mechanism 8 includes a base plate 81, which serves as the mounting base for the bottom lifting power. A cylinder 82 is fixedly connected to the top of the base plate 81. The cylinder 82 is activated by receiving a signal, causing its drive end to extend vertically upward. A fixed plate 83 is fixedly connected to the drive end of the cylinder 82, which is pushed by the cylinder 82 to lift the whole structure. Multiple conveying plates 84 are fixedly connected to the top of the fixed plate 83, thus moving upward synchronously with the fixed plate 83. The power source drives the transmission track or roller structure to push and convey the glass sheet horizontally. The outer walls of the multiple conveying plates 84 are slidably connected to the inner walls of the housing 1 and the cutting table 85. Multiple conveyor belts 7 are provided on the side of the housing 1 near the waste separation zone 6. The power source drives the multiple conveyor belts 7 to relay the transmission with the conveyor plate 84, so that the waste embedded in the finished glass is continued to be transported out along with the finished glass. The multiple conveyor belts 7 have gaps between each other, so that the waste fragments after they are completely broken lose the physical support at the bottom. The waste frame 9 is set directly below the multiple conveyor belts 7, and then uses gravity to allow the waste fragments that can pass through the gaps to fall directly, which is used to receive the waste fragments that fall through the gaps. The multiple conveyor belts 7 are used to support the finished glass to be transported out across the gaps. Two positioning blocks 91 are fixedly connected to one side of the housing 1 to provide a smooth guide track for the bottom collection device to be pulled out. The outer walls of the two positioning blocks 91 are slidably connected to the outer wall of the waste frame 9 to form a drawer-type quick-release structure that can operate efficiently and continuously. Two locking plates 92 are slidably connected to the inner wall of the waste frame 9 to provide structural locking stability after sliding into place. The outer walls of the two locking plates 92 are slidably inserted into the inner walls of the corresponding positioning blocks 91. An operating table 2 is provided on one side of the housing 1, for operators to input CAD drawings and cutting instructions. The operating table 2 is electrically connected to the control system of the device via a signal line 21.
[0021] Please see the appendix Figure 5A control system for a laser cutting device for irregularly shaped glass is disclosed. This control system integrates a trajectory interpolation logic algorithm based on CAD analysis and a multi-step time-series collaborative control model. The control system performs CAD analysis on the CAD graphics input from the operating table 2 to form a cutting trajectory, and performs X-axis and Y-axis linkage interpolation based on the cutting trajectory. The control system uniformly schedules the conveying mechanism, moving mechanism, cutting workpiece, and waste separation zone according to a set time sequence, achieving the following control: The cylinder 82 of the control conveying mechanism 8 is lifted upward, so that the conveying plate 84 passes through the surface of the cutting table 85 and smoothly lifts the glass sheet. The glass sheet is pushed and conveyed to the processing coordinate area by the conveying conveyor belt or roller structure on the surface of the conveying plate 84. After the glass sheet reaches the processing coordinate area, the drive end of the control cylinder 82 moves downward, so that the conveying plate 84 is lowered to below the surface of the cutting table 85, so that the glass sheet is placed flat on the cutting table 85. The drive mechanism 3 performs X-axis and Y-axis linkage interpolation. Through the coordinated straddling movement of the transverse slide rail 31 and the longitudinal slide rail 33, the cutting workpiece 5 is precisely moved to the top of the set cutting trajectory. The cutting workpiece 5 is controlled to sink, so that the ball bearing 54 in the flexible pressure cover 52 contacts the glass first. The ball bearing 54 compresses the spring 53 to flatten the glass sheet on the cutting table 85. The ball bearing 54 and the spring 53 compensate for the micro-undulations of the glass to improve the focal length stability. The laser cutting head 51 is used for cutting. After the laser cutting is completed, the moving mechanism 3 is driven so that the cutting workpiece 5 drives the cleaving execution head 55 to run along the cutting trajectory to induce stress on the micro-cracks generated by the laser cutting. The cutting workpiece 5 is controlled to slide upward along the first vertical slide rail 35, and the cylinder 82 of the conveying mechanism 8 is controlled to lift upward, so that the conveying plate 84 lifts the cut glass and conveys it to the waste separation zone 6; multiple execution components inside the waste separation zone 6 are controlled to locally heat the area around the waste and centrally cool the waste area, so that a temperature difference is formed between the waste area and the surrounding finished product area, and the waste is broken and separated from the finished glass by the effect of thermal expansion and contraction. The control conveyor plate 84 and the conveyor belt 7 relay the transmission, so that the waste material embedded in the finished glass and at the same level moves synchronously with the finished glass. After breaking, the waste fragments that can pass through the gaps between the conveyor belts 7 fall into the waste frame 9 under the action of gravity, realizing the automated collection of waste fragments. The finished glass is supported by multiple conveyor belts 7 and output across the gaps.
[0022] Working principle: First, the operator inputs processing instructions through the control panel 2. When feeding, the cylinder 82 drives the fixed plate 83 to rise, so that multiple conveyor plates 84 pass through the cutting table 85 to lift the glass sheet. The conveyor belt or roller structure on the surface of the multiple conveyor plates 84 pushes the glass sheet horizontally to the processing coordinate area. After the transfer is in place, the cylinder 82 drives the conveyor plate 84 to retract and descend, so that the glass sheet is placed flat on the cutting table 85. Subsequently, the moving mechanism 3 performs the addressing action, the slider 32 drives the support plate 4 to move along the X-axis along the transverse slide rail 31, and the longitudinal slide rail 33 guides the fixed block 34 to slide along the Y-axis. Through the linkage between the X-axis and the Y-axis, the fixed block 34 is moved to the position directly above the cutting trajectory. After positioning, the power source drives the cutting workpiece 5 to sink along the first vertical slide rail 35 as a whole, and the power source drives the second vertical slide rail 36 to descend. The laser cutting head 51 descends with the second vertical slide rail 36, so that the flexible pressure cover 52 outside the laser cutting head 51 contacts the glass first. During the pressing process, as the cutting workpiece 5 descends slightly, the glass presses upward against the ball bearing 54 and compresses the spring 53. The deformation pressure generated by the spring 53 presses the glass flat on the cutting table 85 through the ball bearing 54. When the laser cutting head 51 moves to cut, the ball bearing 54 rolls on the glass. After the cutting is completed, the cleaving head 55 runs along the trajectory to induce initial stress on the microcracks. Then, the cylinder 82 lifts the conveyor plate 84 again to transport the glass with the cut to the waste separation zone 6. When the glass enters the waste separation zone 6, the system locally heats the area around the waste and simultaneously cools the waste area, creating a temperature difference between the waste area and the surrounding finished product area. The thermal expansion and contraction effect is used to break and separate the waste from the finished glass. After the breakage, the glass continues to be transported outward by the relay transmission of the conveyor plate 84 and the conveyor belt 7. When the glass moves onto the conveyor belt 7, the waste fragments that can pass through the gaps between the conveyor belts 7 fall into the waste frame 9 below under the action of gravity and are collected. The finished glass is smoothly output from the conveyor belt 7 across the gaps. Finally, the waste frame 9 is locked by the interlocking cooperation of the clamping plate 92 and the positioning block 91. When it is necessary to clean up the waste, it can be directly pulled out and separated.

Control the moving mechanism (3) to perform X-axis and Y-axis linkage interpolation, so that the cutting workpiece (5) moves to the top of the cutting trajectory; Control the cutting workpiece (5) to sink, so that the ball (54) in the flexible pressure cover (52) contacts the glass sheet and compresses the spring (53), pressing the glass sheet flat on the cutting table (85) and cutting it in conjunction with the laser cutting head (51); The control blade execution head (55) runs according to the cutting trajectory to induce stress in the microcracks generated by laser cutting; The control conveying mechanism (8) conveys the cut glass to the waste separation zone (6). The control multiple execution components inside the waste separation zone (6) respectively heat the surrounding area of the waste and cool the waste area in a concentrated manner, so that a temperature difference is formed between the waste area and the surrounding finished product area, causing the waste to break and separate from the finished glass. The control conveyor plate (84) and multiple conveyor belts (7) relay the transmission, so that the waste fragments that can pass through the gaps between the multiple conveyor belts (7) fall into the waste frame (9) under the action of gravity, and the finished glass is supported and output by multiple conveyor belts (7).
